hi i m planning to write a paper in classical mechanics.Anybody know of any open issues in fluid mechanics?

thanks buddies.the answer correctly comes out to be a(obs) = (2/7)*a. the only problem was due to the relative acceleration between the sphere and the car. also friction need not be equal to (mu)*m*g.the force of friction gets canceled out. thanks anyway.

the a(obs) here is the required acceleration of the sphere with respect to the inertial frame. are the two relations i have mentioned then correct? please help with the second one.with that clear the problem will be simple to solve.

i tried. but i am not getting it.could u be more precise with it please. thanks. since it is rolling without slipping,static friction comes into play. let a(obs) be the acceleration observed in the inertial frame.let f be the force of friction.then f*r = 2/5 m*(r^2)*a(obs)*r now applying...

the sphere is rolling without slipping...thats all that has been given in the problem...does a pseudo force come into play??

hey guys! i have a problem in physics which i could'nt solve: a car is moving with constant linear acceleration a along horizontal x-axis. A solid sphere of mass M and radius R is found rolling without slipping on the horizontal floor of the car in the same direction as seen from an inertial...

the constants in physics are due to the way the physical world behaves.if a constant changes may be we would have a situation where some constants used in equations are replaced by some other ones.that could create a interesting situation.if two constants in an equation are being replaced by...

could u mail it to me.it would be great.

i have a sick library around.wish i could get it on the net.even a modified version will be good for a start,heard its pretty deep.

could anyone post a link to Pauli's original proof of spin-statistics theorem.have been looking for a long time.could'nt find any. thanks.
